Experimental: Group 1: Mepilex on Litter + AE Mattress + 30 degree backrest
Intervention: Mepilex
|
Mepilex Border Sacrum dressing is a multi-layered soft silicone dressing that is a recommended strategy to augment standard nursing interventions (i.e., repositioning, offloading) to prevent pressure injuries.
The dressing will be placed on the sacrum.
|
|
Kein Eingriff: Group 2: Without Mepilex on Litter + AE mattress + backrest
Intervention: Control (no Mepilex)
|
|
|
Experimental: Group 3: Mepilex on VSB on AE mattress
Intervention: Mepilex
|
Mepilex Border Sacrum dressing is a multi-layered soft silicone dressing that is a recommended strategy to augment standard nursing interventions (i.e., repositioning, offloading) to prevent pressure injuries.
The dressing will be placed on the sacrum.

|
Experimental: Group 5 Prolonged Field Care (PFC) - LiquiCell on Talon litter
Intervention: LiquiCell mat
|
LiquiCell is a thin layer of low-viscosity fluid contained in a series of bursa-like pouches.
Baffles within each pouch channel the liquid to disperse pressure and the volume of liquid in the pouch is so small that there is no pressure-build up.
LiquiCell is available commercially as a 36 X 18-inch mattress overlay (LiquiCell Shear Reducing Mattress Overlay) with a soft pliable top and a non-slip bottom.
The overlay is positioned from the shoulders to below the hips to minimize shear.

Kein Eingriff: Group 6: PFC Without LiquiCell on Talon Litter
Intervention: Control (no LiquiCell)

Maßnahmenbeschreibung |
Zeitfenster |
|---|---|---|
|
Change in Interleukin-1/Total Protein (Skin)
Zeitfenster: Baseline through study completion - approximately 120 minutes
|
Skin cytokine (IL-1) and total protein will be obtained using a small strip of specialized tape placed on the sacrum/buttocks.
After 1-minute application the tape is removed and analyzed for quantity of interleukin-1 (indicator of skin irritation)
|
Baseline through study completion - approximately 120 minutes
|
|
Change in Transcutaneous Tissue Oxygen (TcPO2)
Zeitfenster: Measured continuously during the baseline (sidelying), supine (120 minutes) and post-sidelying (15 minutes) periods
|
Tissue oxygen is measured continuously on the sacrum using a noninvasive sensor and on the midsternum (midchest) as a control
|
Measured continuously during the baseline (sidelying), supine (120 minutes) and post-sidelying (15 minutes) periods
|
|
Change in Skin Moisture (Epidermal and Subepidermal)
Zeitfenster: Baseline (before lying down) and after 120 minutes supine
|
Two components of skin moisture will be measured on the sacrum using the Delfin MoistureMeter.
The epidermal moisture, which reflects perspiration and subepidermal moisture , which reflects water content of the tissues.
The values range from 1-80, with higher numbers reflecting increased moisture.
|
Baseline (before lying down) and after 120 minutes supine
|
|
Change in Skin Temperature
Zeitfenster: Measured continuously during the baseline (sidelying), supine (120 minutes) and post-sidelying (15 minutes) periods
|
Skin temperature will be measured continuously on the sacrum using a laser doppler probe.
|
Measured continuously during the baseline (sidelying), supine (120 minutes) and post-sidelying (15 minutes) periods
|
|
Change in Skin Interface Pressure
Zeitfenster: Continuously during the supine phase of the study (120 minutes)
|
The pressure between the support surface and the skin will be measured continuously during the supine position using the X Sensor system.
This system measures force/unit area (e.g., pressure).
The peak and average pressure on the sacrum/buttocks will be measured.
|
Continuously during the supine phase of the study (120 minutes)

|
Change in Pressure-Discomfort (Category Partitioning Scale-50)
Zeitfenster: The score will be obtained at baseline and every 30 minutes in the supine position (total 5 measurements).
|
This scale asks the participant to describe in verbal terms the pressure intensity or discomfort associated with the stimulus (i.e., sacral/buttocks pressure or discomfort).
The participant can then fine tune their assessment using a numeric score.
The final score is an analog.
The score ranges from 0-52, with higher scores indicating higher pressure or more severe discomfort.
The investigator will ask the participant to limit their evaluation to the pressure/discomfort sensed on the sacrum/buttocks, but the investigator will also ask the participants to identify on their body where they are experiencing the most pressure/discomfort.
|
The score will be obtained at baseline and every 30 minutes in the supine position (total 5 measurements).
